The correct answer is: B. Synapse<\/strong><\/p>\n A synapse is a junction between two nerve cells, or neurons, across which nerve impulses pass. A synapse is essentially a gap, across which neurotransmitters are released from the axon terminal of one neuron and bind to receptors on the dendrites of another neuron. This binding of neurotransmitters causes the postsynaptic neuron to either fire an action potential or not fire an action potential.<\/p>\n An axon is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the cell body. Axons are typically covered in a fatty substance called myelin, which helps to insulate them and speed up the transmission of nerve impulses.<\/p>\n Neuroglia, also known as glial cells, are non-neuronal cells that support and protect neurons. Neuroglia make up about 50% of the brain’s volume and perform a variety of functions, including providing nutrients to neurons, removing waste products from neurons, and forming the blood-brain barrier.<\/p>\n Dendrites are short, branching projections of a nerve cell, or neuron, that receive electrical signals from other neurons. Dendrites are typically covered in receptors that bind to neurotransmitters released from axons. When neurotransmitters bind to receptors on dendrites, it causes the neuron to either fire an action potential or not fire an action potential.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Axon” option2=”Synapse” option3=”Neuroglia” option4=”Dendrites” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15],"tags":[],"class_list":["post-47560","post","type-post","status-publish","format-standard","hentry","category-biology","no-featured-image-padding"],"yoast_head":"\n
